Chris Cooke led from the front with 205 not out as Glamorgan spent day two of their LV= Insurance County Championship second division match against Surrey constructing a total of 672 for 6 declared, the home side responding with 45 for no wicket in the final hour.
Cooke was joined by Dan Douthwaite in a 51-over sixth wicket stand of 189, and that followed a slightly more urgent partnership of 140 in 37 overs with Kiran Carlson, who was on 45 overnight and reached 69 before being quite brilliantly caught by a diving Dan Moriarty at square leg as he swept hard at Will Jacks’ off breaks.
Douthwaite was eventually caught at long on by Jacks soon after tea, for a curiously-restrained 146-ball 59 that contained only two fours, giving off spinner Amar Virdi a hard-won third wicket.
On a surface showing little sign of predicted turn, Glamorgan resumed on 379 for 4 and accumulated ruthlessly, if perhaps over-cautiously, in warm sunshine before declaring.
The declaration, greeted by some ironic cheers, left Surrey 15 overs to bat before stumps, and openers Jamie Smith and Ryan Patel reached 23 and 22 not out respectively.
Cooke, who began the day on 44, batted for five minutes short of six hours, facing 299 balls and hitting a six and 18 fours.
It was his eighth first-class score of 100 or more and, as Surrey manfully and quite successfully kept as tight a control as they could on Glamorgan’s scoring rate, Cooke added an unbeaten 54 for the seventh wicket with Callum Taylor, who swept Jacks for six and also in the same over cover drove and cut him for fours in a breezy 57-ball 38 not out.
